'Sum' Notation?

I looked throuh the latex forum, but I can't seem to get the latex to note this correctly:

n

r=1

Above, I typed the n above and the R=1 beneath, but in a question, the sum notation is in the middle of the question, so I don't have this option. :s.

Thanks in advance for any help.

Double click on the Sigma notation to see the Latex code used to generate it.

Thanks for the fast response.

You can also do it this way:

\displaystyle \sum_{r=1}^n
